ENVELO P.

SPECIFICATION forming part of Letters Patent No. 565,470, dated August11, 1896.

Application filed July 11, 1895.

To all whom it may concern:

Be it known that I, OLE E. LEE, of Oelwein, Fayette county, Iowa, haveinvented certain new and useful Improvements in Envelops, of which thefollowing is a specification.

My invention relates to envelops for sending money and valuable papersfrom place to place for the use of banks and express companiesparticularly, and the object I have in view is to provide an envelopwhich will be cheap to manufacture, which it will not be necessary toseal, and which cannot be tampered with without detection.

My invention consists generally in various constructions andcombinations, all as hereinafter described, and particularly pointed outin the claims.

The invention will be more readily understood by reference to theaccompanying drawings, forming part of this specification, in Which-Figure l is a plan view of an envelop embodying my invention, showingthe same open ready for use. Fig. 2 is a similar view showing theenvelop closed. Fig. 3 is a plan view of the opposite side of theenvelop, showing the thread beneath the surface of the same. Fig. 4 is amodification, the flap being arranged on the end of the envelop and thethread running longitudinally across the face of the same instead ofcrosswise, as in the other views. Figs. 5 and 6 are detail sectionalviews showing the thread or cord embedded in the material of which theenvelop is composed.

In the drawings, 2 represents an envelop of the ordinary shape and sizemade in the usual manner and provided with the flaps 3 and 4 upon itslongitudinal edges. The flap 4 is sealed, as is usual, while the flap 3is turned back to permit access to the interior of the envelop. A thread5 is embedded in the material composing the envelop crosswise of theface of the same, having its free ends turned over the longitudinaledges of the envelop and adapted to be brought together and tied overthe flaps 3 and 4 on the back of the envelop. A small space ispreferably left between the adjacent edges of the flap to re- Serial No.555,649. (No model.)

ceive the knot formed by the ends of the thread 5. After the knot hasbeen securely tied the ends of the thread are cut off close to it andthe knot pressed into its place between the flaps, where it will be outof the way and in no danger of catching on another envelop or any otherarticle.

After the money or papers have been placed in the envelop, the flapclosed, and the knot tied and the ends of the thread cut off it will beimpossible to tie the thread again if untied, and hence any attempt toopen the envelop after it has once been tied up will be instantlydetected, whether the knot be untied or whether the thread or string 5be entirely removed.

I do not confine myself to the use of the envelop with the flap upon itslongitudinal edge, as my invention is as Well adapted for use on anenvelop having a flap on its end, as shown in Fig. 4. that the flaps beof the same size, that they meet exactly in the middle of the envelop,or that there be a flap upon each of the longitudinal edges or upon theends of the envelop.

- By using this device it is not necessary to seal the package or sewthe money or papers into the envelop. The thread or string is placedbeneath the surface of the envelop While it is being manufactured andany attempt to remove it would be noticed by the most casual observer.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. An envelop having athread or cord embedded in thematerial composing the same, the ends of said thread being out close tothe knot formed by tying the free ends of said thread or cord together,thereby forming a seal for said envelop, substantially as described.

2. An envelop, having a thread or cord inserted between the layers ofpaper or other material composing the same and extending across the faceof the envelop and the flaps provided on the longitudinal edges thereof,the ends of said thread or cord being cut close to the knot formed bytying the free ends of It is not necessary either said thread, therebyforming" a seal for said envelop, substantially as described.

3. An envelop having a thread extending around it, and embedded in thematerial (301D- posing the same, the ends of said thread being out closeto the knot formed by tying the free ends of the same, thereby forming aseal for said envelop, and said knot being pressed into the spaceprovided between the edges of the flaps, for the purpose set forth. :0

In testimony whereof I have hereunto set my hand this 6th day of July,A. D. 1895.

OLE E. LEE. In presence of C. G. HAWLEY, RICHARD PAUL.
